FC9 : DVD ROM detection and writing
 

Hi,

I have Fedora release 9 (Sulphur) in TEXT ONLY mode.

I have a Samsung DVD writer connected to it.

I want to backup my data to a DVD.

I have 2 hurdles:
(a) How do I detect my DVD rom drive and mount it.
(b) How do I write data to the DVD.

I am relatively new.

Please suggest pointers or steps.

Thx
Vai

One straightforward way is to look through /var/log/message where the loading kernel detects its hardware

Newer systems usually have some hotplug functionality. You can just insert a dvd, close the drive, and wait for a popup to ask what you want to do with it. Say open and the file manager will show its contents. Now "mount" will show you the name of the device and where it is mounted.

I scanned the /var/log/messages but I would not figure-out what to look for and how to idenitfy the DVDROM.

Is this the DVD ROM ??

What next ??

Thx
Vai

Here's how I would do it.
First run 'lsscsi':
So in this case the drive is /dev/sr0. Usually there's a symlink from /dev/cdrom, so you can use that too, but not if you have more than one DVD drive.

You can also find out more info on the drive using:
Now, to burn your data you do NOT need to mount the disk, in fact you can't, it's impossible.

To write the data, read about it here:
http://www.linux.com/feature/113859

Or you can use my script:
http://draconishinobi.50webs.com/sla...ul-scripts.tgz
It's called 'burnit' just run 'burnit directory /dev/sr0'.
Or just run:
Where source_directory is the directory you want to burn, and with the appropriate speed setting (here it's 1x)

Thx for your details ionstructions.
I am sure it will be of great help.

When I hit lsscsi I got this error.

[root@server ~]# lsscsi
-bash: lsscsi: command not found


Is lsscsi not included in the std FC9 distro or have I stopped some services ??

Thx for your help.

Vai

It's probably not included, in which case, how many DVD drives do you have ? If only one, then use /dev/cdrom or /dev/dvdwriter those symlinks should be there

I have 1 ROM.

But the output id different.

The outpur of lsscsi is as follows:

I will just check if the ROM is well connected and showing up in CMOS.

It doesn't seem to be detected.

Figured out the ROM was not powered & its a CD ROM not DVD :(

Now I see this.

and I see this:

So now I have recognised the ROM.
Now the burning part....

I will try this command to test a burn

But 1 question, how do I define multiple files & folders in the command ?
Is it like
Or is there any other way ?



Thx
Vai

FC9 does not have growisofs

FC9 does not have "mkisofs" either which is required for "growisofs".

Please help, what utility should I use/install for CD/DVD burning in FC9

Thx
Vai

You can also use cdrecord to burn a DVD, I've never done it tho, I prefer growisofs. But you'd probably run this:

To burn more than one directory just list the rest of them after that first one.

But, as you will notice from the above, you cannot backup data files to a data dvd or cd without mkisofs ... you can't make an iso ... therefore what are you gonna burn ? Nothing. Therefore you must first install mkisofs, and I recommend growisofs too.

I believe it's part of the dvd+rw-tools package.

Ok.

dvd+rw-tools package does not include mkisofs
See this:
So I had to first install genisoimage-1.1.6-11.fc9.i386.rpm & then dvd+rw-tools-7.0-11.fc9.i386.rpm

But this could not burn a CD.


What are my options to burn a CD ?

Thanks for your continued help.
Much appreciated.

This seems to be your CD-ROM drive:
http://www.google.com/products/catal...#ps-tech-specs

I assumed it was a DVD burner, but ... it cannot read DVDs, it cannot burn at all (not CDs or DVDs) ... is this the only one you have ?

If this is not your drive then post the output of:

If it is your drive, you need another drive, one that can burn DVDs.

Hi,

Finally I managed to burn my First DVD.

On FC9 I had to do the following in order:

Installed the following rpm for CD/DVD detection and burning
(1) lsscsi-0.19-1.i386.rpm
(2) genisoimage-1.1.6-11.fc9.i386.rpm
(3) dvd+rw-tools-7.0-11.fc9.i386.rpm

My DVD writer was detected as follows:
Not sure why it was not showing /dev/???

Next, run this command to burn a DVD:
My first DVD is ready!!

I hope this small writeup will help other newbies like myself.

Thanks to all forum members for their help.
Special thanks to "H_TeXMeX_H" for his inputs & support.

I have a quick question.

When I executed the following command, the files & folders from /var/www/html got written on the DVD.
I was expecting the folder "html" to be created on the DVD and then the content to have been copied inside the html folder.

What did I miss ??

Thx
Vai

Alright, well either way, you can usually use the symlinks made by udev:

/dev/dvdwriter

if there are more than one they will be labeled:

/dev/dvdwriter0
/dev/dvdwriter1

same goes for cdwriter, cdrw, dvdrw, cdrom, dvd

You may also want to read here for more info:
http://www.linux.org/docs/ldp/howto/...-HOWTO/sr.html

If you're using an IDE drive it may be detected as /dev/hdd, while for SATA drives it will be /dev/sr0.

EDIT:

As for your question, that command will write the directory you point it to to the root of the iso, so if you want to keep the html directory, you have to put it in another directory and point it to that. Whatever directory you point it to will not be created, it will became the root or / of the iso, so make sub-directories.

hmm..
How to copy "Folder" (with Files & folder inside)
Rather than copying all files and folders of a folder ??

I hope this is understandable.

Vai

Sorry I don't get it.

Just do:
Then burn dvd directory.

Let me explain.

When I wrote my first DVD, the source was defined as -> /var/www/html
I was expecting "growisofs" to create a folder "html" on my DVD and then copy all files inside that folder.
Instead, "growisofs" copied all files from "/var/www/html" into the base of DVD.


OR in simpler words, how can I "folders" on DVD and contents inside the folder

Thx
Vai

Let me give another example:

I have a folder fld1 which contains 3 files.
a.sh
b.sh
c.sh

I would like to copy the entire folder "fld1" to my DVD, such that my DVD should look like this:
/mnt/dvd/fld1/a.sh

I see, ok you can try this instead:

see here for description:
http://wiki.archlinux.org/index.php/DVD_writing

hmm. I will try this...

One last question in this series.

Is it possible create a text file with a list of all folders & files which need to be burnt on DVD and then call it from the command prompt.

For example:

File = MyBackupList.txt
Then call "MyBackupList.txt" with the "growisofs command.

Thx again for your contants help.

I think you can just run:

Surprisingly, I am unable to write more than 200MB of data.
The DVD is a 4.7GB capacity.

What am I missing?

I get this output at the end:

I think it wrote all the data you gave it, which was probably 194 MB worth. If you give it more data it will write up to around 4500 MB.

If you want to know the size of what you're gonna be burning run mkisofs this way:

it will give you the size in MB of the data to be written.

Hi,

I am using the below command for writing data to a DVD and its working great in production environment.

I am facing 2 minor issues:

(a) I see a folder called "RR_MOVED".
I do not want this to be written on the DVD.
How can this folder be avoided from writing on the DVD.

(b) How can I set a name/label to the DVD when writing.

Thanks again to forum members for continued support.

Best regards,
Vai

From the man page:

Your choice as to which option to use.

so, add these options after '-iso-level 2'.
